In-Kind Contributors

The CTAO requires the collaboration and investment of a wide international network of countries and contributors. The CTAO Central Organisation benefits from several major contributions from In-Kind Contribution (IKC) teams, who provide people, goods and services for the software and hardware development and construction of the Observatory.

Telescope Collaborations

Of the many IKC teams involved in the CTAO, the three telescope collaborations are the most substantial. These massive groups of scientists and engineers from institutes that span the globe are providing components, as well as expertise, to develop the CTAO’s detectors.

The Large-Sized Telescope (LST) Collaboration is made up of over 400 scientists and engineers from 67 different institutions across twelve countries: Brazil, Bulgaria, Croatia, Czech Republic, France, Germany, India (dormant), Italy, Japan, Poland, Spain and Switzerland.

Work Package Leader: Masahiro Teshima

Co-Work Package Leader: Juan Cortina

Work Package Manager: Daniel Mazin

The Medium-Sized Telescope (MST) is being built by an international collaboration of institutes and universities from Austria, Brazil, France, Germany, Italy, Poland, Spain and Switzerland.

Structure Coordinator: Markus Garczarczyk

FlashCam Coordinator: German Hermann

The Small-Sized Telescope (SST) will be built by an international collaboration that includes research institutes and universities from Australia, Brazil, France, Germany, Italy, Japan, Netherlands, Switzerland and UK.

SST Coordinator: Gianpiero Tagliaferri

SST Camera: Richard White

Computing Contributors

The CTAO Central Organisation’s Computing Department is charged with designing and implementing a system that supports everything from accepting observation proposals to scheduling observations, controlling the telescopes, processing and archiving the data at all levels and disseminating data products and science tools to the public using open standards and FAIR (findability, accessibility, interoperability, and reusability) principles. 

Because such a computing system does not exist as a stand-alone product, the work required covers all steps, from architectural design to construction, validation, deployment and maintenance. The technical challenges and long lifetime of the Observatory necessitates the development and adoption of new techniques and technologies to meet the scientific demands, as well as a workforce of about hundred software experts over five years to build the software systems. This would not be possible without the support of a wide range of contributors. IKC providers deliver software, computing infrastructures and hardware, integration and verification, as well as support for coordination. Here is a summary of the contributing groups:
